I've got my comb set pretty high but the gun doesn't fit quite right. If I lower the comb the gun fits better but I seem to go clear through a target and shoot over it. Any suggestions on what I should do?

Kgun, Set your gun up for fit first. For example, is the bead in line with your eye's pupil? Then put the trap machine on straight away targets, stand on about the 20-22 yrd line and shoot targets adjusting your comb for the correct point of impact. You should be centering about 80% of the targets and taking the top out of the other 20%. I hope this helps you.

The solution to your problem, kgs, can only be found when you, yourself, by force of will, added concentration on the task, and increased control of where the gun is pointing, quit shooting over the target.

No, dean, and I'm sorry it may have sounded like that. What I am advocating to kgs, as well as to anyone who consistently puts the gun in the wrong place, is to stop putting it in the wrong place and instead put it in the right place. The gun, after all, does not have any powers of movement of its own; it is aimed somewhere by the shooter. It's the task of the shooter to do that correctly and can only be done if the shooter takes control and simply quits doing the wrong thing and starts doing the right one. No other advice will solve his problem.

your swinging the gun up while your head has stopped moving with it,and thats because the comb hasnt bottomed out on your cheek enough,because if it did it would push up your head with it,then you would realise your barrel is up over the target sooner.
you should be locked in,cheek to comb and eyes over rib,and the whole thing moves in unison like an m1 abrams tanks turret.
just my WAG.
